Abstract

Mengening Beach is located in Badung Regency, Bali, Indonesia. The average erosion rate in Badung Regency is 1.96 m/year, so the right plan is a submerged breakwater to reduce wave energy coming to the beach, which causes erosion. This building artistically does not lessen the beauty of the beach and sea because it’s below the sea mean sea water level (MSL). Because the beach is a tourist area, it is essential to maintain the beauty of the beach. Two-dimensional wave modeling uses the CMS Wave model on SMS software version 10.1 with two modeling scenarios: before and after there is a submerged breakwater. The two-dimensional wave results show that the submerged breakwater plan can dampen waves in the building placement area, which was initially 1.3 m-1.4 m high to 0.9 m-1.3 m, so this submerged breakwater plan can reduce waves by 10%-40%. From this research, readers can learn how to plan a submerged breakwater and know the performance of the planned breakwater function at Mengening Beach.

Abstract

Canggu Beach, Bali, is a multifunctional coastal area that faces environmental pressures due to erosion and rapid coastal development. This study analyzed shoreline changes during the period 2016-2024 using multitemporal Sentinel-2 satellite images processed through the Google Earth Engine (GEE) platform. Shoreline extraction was performed using NDWI index and Otsu threshold method, with sea level stability control based on HYCOM data. Shoreline change analysis was conducted using Digital Shoreline Analysis System (DSAS) on 247 transects with Net Shoreline Movement (NSM) and End Point Rate (EPR) approaches. Results showed a dominant trend of accretion (NSM +16.61 m; EPR +2.26 m/year), with localized erosion (NSM -8.8 m; EPR -1.2 m/year), identified around estuary and structured areas. Spatial patterns of change were visualized in the form of multitemporal maps and statistical histograms, revealing uneven shoreline dynamics. The integration of GEE and DSAS proved effective for large-scale shoreline monitoring, and the results can provide a basis for adaptive coastal management in dynamic, multi-functional coastal areas.
